ABSTRACT / САЖЕТАК:
This study examines how the addition of NPK fertilizers impacts the change in Nardus stricta type grasslands. The investigation was carried out on the mountain Kopaonik between 2009 and 2012. The effects of four fertilizing treatments: control; N60 (N60P60K60); N90 (N90P60K60); N120 (N120P60K60) on plant species composition, Shannon evenness, and EGQ (evaluation grassland quality index) were researched. The control treatment was dominated by Nardus stricta species, while Festuca rubra and Agrostis capillaris presence was a feature of fertilizing treatments. The highest nitrogen intake (N120) had Shannon evenness that was very similar to that of the control. All fertilizing treatments resulted in increasing forage value.
